The Indian Space Research Organisation (ISRO) has achieved another leap in its quest for self-reliance in space, successfully launching the heaviest communication satellite ever lifted from Indian soil using its formidable heavy-lift rocket, the Launch Vehicle Mark-3 (LVM3). Affectionately nicknamed ‘Bahubali’ for its sheer power, the LVM3-M5 mission placed the critical 4,410 kg CMS-03 spacecraft into a precise Geosynchronous Transfer Orbit (GTO) on Sunday, November 2, 2025, from the Satish Dhawan Space Centre.

With this, he showed us that the Universe is expanding. Towards the end of the last century, scientists discovered something even more surprising. When they more carefully studied how fast nearer and farther galaxies are moving away from us, they found that the Universe is not just expanding, but that the rate of expansion is increasing.
